Pine script 用EMAs进行Pinescript回溯测试

这个脚本有什么问题

这是我想要的

当5个均线在10个均线以下交叉，10个均线在150个均线以下交叉时，做空我的仓位

当5个均线跨越10个均线时覆盖

请说明我遗漏了什么

谢谢

ema5 = ema(close, 5)
ema10 = ema(close, 10)
ema150 = ema(close, 150)

plot (ema5, title ="EMA5", color = color.green, linewidth = 2)
plot (ema10, title ="EMA10", color = color.red, linewidth = 2)
plot (ema150, title ="EMA150", color = color.black, linewidth = 2)

_5CrossesUnder10 = crossunder(ema5, ema10)
_10CrossesUnder150 = crossunder(ema10, ema150)
ShortCondition = _5CrossesUnder10 and _10CrossesUnder150

_5CrossesAbove10 = crossover(ema5, ema10)

// plot(close)

strategy.entry("Short", strategy.short, 1, when= ShortCondition)
strategy.close("Cover", when= _5CrossesAbove10)```

这应该起作用：

//@version=4
strategy("My Strategy", overlay=true)
ema5 = ema(close, 5)
ema10 = ema(close, 10)
ema150 = ema(close, 150)

plot (ema5, title ="EMA5", color = color.green, linewidth = 2)
plot (ema10, title ="EMA10", color = color.red, linewidth = 2)
plot (ema150, title ="EMA150", color = color.black, linewidth = 2)

_5CrossesUnder10 = crossunder(ema5, ema10)
_10CrossesUnder150 = crossunder(ema10, ema150)
ShortCondition = _5CrossesUnder10 and _10CrossesUnder150

_5CrossesAbove10 = crossover(ema5, ema10)

// plot(close)

strategy.entry("Short", strategy.short, 1, when= ShortCondition)
strategy.close("Short", when= _5CrossesAbove10)

啊。。非常感谢，我真的很感激
